I have PKZip on my computer and when I double-click on a zipped file the file will extract but when I double-click on Quickstart_helloworld_action.esb a question comes up about whether I want to open it or not (not the normal PK behavior) and then when I click "open" nothing seems to happen. Is there a standard way of opening this and viewing the contents?

Maybe the easiest way would be renaming the file to Quickstart_helloworld_action.zip, and open it with PKZip afterwards. Or, in case you have Total Commander installed, you can just hit the Enter key on the .esb file and it will "go into" the contents of the packaged file.

Thank you, Miklos, that worked and I can see the META-INF and org folders along with the jbm-queue-service.xml. The org folder has classes buried deep down inside of it and the META-INF folder has deployment.xml, jboss-esb.xml and MANIFEST.MF If that all sounds right then you've solved that problem. Thanks,
